    <p>
        The funnel chart can be used to show stages in a sales or order process, from initial lead/contact through to actual sale.
        It works well if you have a diminishing process, like that shown below. It can show potential revenue in each stage, or
        like below, it can show actual numbers. It can also highlight potential problems in an organisations sales and/or order fulfillment
        processes.
